These windmills are very useful if you have a few thousand. The windmills can stay upright. The wind can't knock them over because the windmills are made from a special nickel alloy. These windmills are only two millimeters tall! They have three blades with a 1.8 millimeter diameter. These micro windmills are very cheap to make. Jung-Chih Chiao, an electrical engineering professor at the University of Texas, is the inventor of these tiny windmills. The windmills can be made with only one wafer. In conclusion, the windmills are very cheap and handy because you can use them to charge your phone for an emergency call.
